As buildings have become tighter with improved building envelope systems and inoperable windows to minimize energy use, IAQ and IEQ have become primary considerations for professional engineers and architects.

HEPA filters are 99.999% effective at removing particulate 0.3 micron and larger.

As hospitals address this need for space, they must also consider the need for isolation rooms suited for behavioral health patients.

Engineered Infection Prevention mitigation strategies usually include dilution (ventilation), filtration, humidification, and air cleaning and disinfection.

Steps building managers and design engineers can take to minimize risks.

The value of appropriate ventilation systems should not be underestimated.

The success of any filtration system depends upon its ability to capture the right contaminants in the right quantity whilst presenting the lowest resistance to the airflow.
